i'm installing some new flowtech headers on a 1987 350 TPI engine. but i notice each side has two connections the new headers dont have anything to connect too. i say i ordered them right but you never know anything can happen. or if thats how it suppose to be tell me what can i do to close lines.

 

Is this the part #BIG-11102FLT

These are the only Flowtech showing a proper fit from Summit.

 

well i got the second from last. the ones that cost around $346.

and it doesn't have two connections it has three on each side.

 

Your stock Y-Pipe only has a two bolt flange, and these headers have 3 bolt flange. If what you ordered was different from what you received, you can call customer service and ask them for the right pair, OR, you could get an aftermarket Y-pipe to fit. Flowtec makes a 3" one with a 3 bolt flange that is decent quality and like $90. I got one for my Camaro and I am happy with it. You should see how restrictive the stock one is anyhow, it resembles this:




If I were you, I'd go for the new pipe if you can afford it. Those headers will see no gain behind a restricted stock system anyhow. You are only as strong as your weakest link, and this is especially true for exhaust.

 

Wow! You gotta be kiding me. That is very restricted. My headers came w/Y-pipe. I got these Edelbrock $399 for mine. I'm wondereing if these have a good reputation or what. I didn't do a lot of research when I ordered these. Anyone have them that got a dyno after?

Could be you ordered headers without the A.I.R. fittings which are part of the stock emission. Thats whay you have connections and nothing on the new headers.

 

Yea, see the A.I.R. pipes???????

 

Yea and don't get your shor hairs in uproar. Mayby you bougth some crap.

 

Now is that because of the air? I have to pass emmission for another 3 years. They are being installed soon. Isn't a 3" tube a 3" tube? They are going to remove any restrictions in the pipes.

 

Ah I gotchya now, thats what you were referring to, the AIR system.

Depending on where you live, you can ditch the AIR and still pass emissions. In NJ all they do is a sniffer, no underhood visual, and I passed all emission numbers with flying colors with my entire system removed.

Definately worth the uncluttering of the engine bay.
